Hi tech@,

Here is a diff to add support for PSF2 fonts detection. From NetBSD.

Reference: https://cvsweb.netbsd.org/bsdweb.cgi/src/external/bsd/file/dist/magic/magdir/linux

Currently, file returns "data" for PSF 2 fonts:

$ file *.psfu
spleen-12x24.psfu: data
spleen-16x32.psfu: data
spleen-32x64.psfu: data
spleen-5x8.psfu:   data
spleen-6x12.psfu:  data
spleen-8x16.psfu:  Linux/i386 PC Screen Font data, 512 characters, Unicode directory, 8x16

With the diff applied:

$ file *.psfu
spleen-12x24.psfu: Linux/i386 PC Screen Font v2 data, 512 characters, Unicode directory, 12x24
spleen-16x32.psfu: Linux/i386 PC Screen Font v2 data, 512 characters, Unicode directory, 16x32
spleen-32x64.psfu: Linux/i386 PC Screen Font v2 data, 512 characters, Unicode directory, 32x64
spleen-5x8.psfu:   Linux/i386 PC Screen Font v2 data, 512 characters, Unicode directory, 5x8
spleen-6x12.psfu:  Linux/i386 PC Screen Font v2 data, 512 characters, Unicode directory, 6x12
spleen-8x16.psfu:  Linux/i386 PC Screen Font v1 data, 512 characters, Unicode directory, 8x16

Comments? OK?
